We're dividing 166510 by 67 
The aim is to understand the frequency of 67 in 166510.

Going ahead to step 1:
67 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 67

Step 2:
16 divided by 67 is 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 67

On to step 3:
When dividing 166 by 67, we get 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 134 away from 166, we end up with 32.
Append the next digit (5) from the dividend to 32 and continue with: 325 / 67

Step 4:
325 divided by 67 is 4 with a remainder of 57.
Put 4 as the next digit of the answer. 
Result so far: 24.0
The remainder is 57 after subtracting 268 from 325.
Append the next digit (1) from the dividend to 57 and continue with: 571 / 67

Step 5:
When dividing 571 by 67, we get 8 with a remainder of 35.
Put 8 as the next digit of the answer. 
Result so far: 248.0
Deduct 536 from 571 and we're left with 35.
Append the next digit (0) from the dividend to 35 and continue with: 350 / 67

Going ahead to step 6:
67 goes into 350 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 2485.0
If we take 335 away from 350, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
The number 67 fits into 150 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 2485.2
Subtract 134 from 150 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
When dividing 160 by 67, we get 2 with a remainder of 26.
The next digit of our result is 2. 
Result so far: 2485.22
Deduct 134 from 160 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 2485.22 with a remainder of 0.026.
